Calculate the hash value using Folding Method for keys 1921678, 777281, 1892, 1921, 21017 for hash table with 1000 memory locations. PLEASE HELP SIR. THX.

Use the table below to convert a character key to an integer for the following questions. Letter A B C D E FG HIJK L M Key Letter 0 12 3 456 789 10 11 12 NOPQ RSTUVWXY Z 13 14 15 16 17 18 19 20 21 22 23 24 25 Key Give the contents of the hash table that results when the same keys are inserted in that order into an initially empty 13-item hash table. Use h(k) = k mod 13 for the hash function for the k-th letter of the alphabet (see above table for converting letter keys to integer values). Use donble hashing and let h'(k) =1+ (k mod 11) be the secondary hash function.

There are N numbers of visitors in Muscat festival, Manager wishes to search particular visitor information based on visitor ID. Consider the records are already arranged in ascending order based on visitor ID. Use this scenario to answer the below assignment questions. 1. Explain the steps for the following operations using binary search. Search for any visitor ID which is available in the list. And Search for any visitor ID which is not available in the list. 2. Use Mid-Square Hashing Technique to explain the following. a. Place all the records into the hash table. b. Use linear probing or chaining technique to eliminate collision. 3. Write your own hash function. Note: N value must be at least 7 . And Use your own data for visitor ID and it must be 4 digit number.

Q4: Based on MD5 hash algorithm, if we used 31 blocks and the padding size is 24 bytes. Find the message size. Q5: The password may contain UPPERCASE, lowercase, octal numbers, and following special characters "&, ?, %, #" find total possible combination number of password that contains 8 non repeated characters.

In your initial post, describe the function of hashing tools you can use to verify that two files are identical. For example, you can compare the hash value of a file on a website with the hash value of that file after you download it. If the hash values match, you downloaded the unmodified version of the website file. Research and discuss at least two examples other than the one provided.

What is the purpose of a hash function in hash table data structures?

Track Addresses Employee Key Values 1234 ЕMP6 ЕMP8 EMP10 EMP12 5678 ЕMP14 EMP16 EMP19 EMP20 9101 EMP26 EMP27 EMP28 EMP29 1121 ЕMP31 ЕMP38 EMP40 EMP42 Index file 1 a. How many comparisions are required to find EMP38 in index file 1 given above b. Update index file by inserting a new employee with employee no. 41. Recreate the index file after updating the index file c. Visualized by recreating the index file how can we reduce camparision to find EMP38

Construct a hash table for storing and retrieving data related to the residents of Oman. The civil number of residents stored using Folding Hashing. Assume that the array size is 10 and the civil numbers are 12038811, 31018131, 04117643, 12345679, 12345672. Find the Key value for each civil number after applying folding and division hashing.

Assume you have a data set containing 100,000 records and you want to perform a search operation using a hash table with a load factor of 0.7. What is the minimum size of the hash table required to store all the records?

When a hash function of 12 bits is used, what is the maximum integral key that can be used to identify the pieces of data that are stored in a DHT? Question 36 When designing a DHT you are expecting to be required to store 1,706,091 elements over its life time. That is the optimal size of the hash output should you use?

PARTS file with Part# as the hash key (K) includes records with the following Part# values:2360, 3760, 5232, 4692, 4871, 2659, 1821, 3074, 7115, 1620, 2428, 1943, 4750, 2975, 4981, 1111, 3123, 3211, 5654, and 2208.
